概括
这次审查在肉类的试验中发现了很少的肌肉特异性基于血液的生物标志物 (BBM). 干预措施对大多数BBM的影响有限,突出显示在萨科佩尼亚管理中需要标准化生物标志物评估.
科学领域:
- 老年学和运动科学
- 生物标志物发现和验证
- 临床试验方法论 临床试验方法论
背景情况:
- Sarcopenia 管理研究往往缺乏对基于血液的生物标志物 (BBM) 的标准化评估.
- 识别频繁报告的BBM及其对干预措施的反应对于推进肉类症护理至关重要.
- 目前的随机对照试验 (RCT) 显示BBM评估的变化,阻碍了比较分析.
研究的目的:
- 为了确定RCT中用于治疗肉症的RCT中最频繁报告的BBM.
- 评估萨科佩尼亚干预措施对BBM度的影响.
- 突出在未来的肉症研究中需要标准化的BBM评估.
主要方法:
- 在2024年3月之前发表的RCT的系统审查和元分析.
- 纳入标准:患有肉症的老年人,共识定义,干预前后的BBM值.
- 对BBM进行的元分析报告在≥2个RCT中使用随机效应模型 (标准化平均差异).
主要成果:
- 在58个 (36.2%) Sarcopenia RCT 中,只有21个评估了BBM;没有一个涉及药理干预.
- 确定了47种不同的BBM;C-反应蛋白,互白素-6和瘤坏死因子-α是最常见的.
- 胰岛素样生长因子1 (IGF-1) 在干预过程中显著增加 (SMD=0.46),但仅限于改善了肉症测量措施的研究时,这一点并不显著.
结论:
- 在肉症RCT中评估的肌肉特异性BBM很少,有限的生物标志物对干预有反应.
- 迫切需要对评估在肉症RCT中肌肉特异性BBM的标准化建议.
- 为改善疾病管理,制定标准化萨科佩尼亚干预研究的核心成果集至关重要.

529
Cardiac biomarkers are critical in diagnosing, prognosing, and managing cardiovascular diseases. Routine measurement of specific biomarkers such as B-type natriuretic peptide (BNP), C-reactive protein (CRP), and homocysteine (Hcy) is common practice in clinical settings to evaluate heart function and predict cardiovascular events.
These markers indicate stress or strain on the heart muscle:
Natriuretic Peptides (BNP)
Cardiac myocytes produce these hormones in response to ventricular stretching...

Cardiac biomarkers are enzymes, proteins, and hormones released into the blood when cardiac cells are injured. They are powerful tools for triaging.
The essential diagnostic tools for detecting myocardial necrosis and monitoring individuals suspected of having acute coronary syndrome (ACS) include:
Troponins
Troponins, particularly cardiac troponins I and T, are the most precise and sensitive markers of myocardial injury. They are detectable within 4-6 hours of myocardial injury and remain...

Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
